From: Thierry Reding <tred...@nvidia.com>
None of the drivers use this in legacy mode, so it can be converted to
use struct drm_crtc * directly. While at it, also make the sole user of
the callback, drm_calc_vbltimestamp_from_scanoutpos(), pass through the
CRTC directly.

Note: This is compile-tested only. It is a straightforward conversion so
I wouldn't expect any fallout, but it'd certainly be best if this can be
tested on all three drivers.
